Our S(D)G series dry type, iron core Transformers and Reactors
adopt high quality low loss silicon sheet and arranged non-bobbin
coil winding technology, and we apply vacuum pressure
impregnating(VPI) process and solidify baking process to achieve
insulation class H or C. Our transformers are widely used on any
occasions where voltage is below 1000V and capacity up to 2000KVA,
and equipment which require voltage to step up or down. Our
Reactors are used in a large variety of applications and in many
industrial activities from phase-shifting to harmonic suppression.

Three phase or single phase dry-type low voltage (LV) transformers
are used as isolation transformers or to adjust the voltage level
in the LV distribution grid. We have advanced technology and
imported equipments and made of high quality silicon sheet,
copper/aluminum enamel insulated wire(or high quality foil),
insulation material and optimal design. Applied with arranged
non-bobbin coil winding technology and Vacuum Pressure
Impregnation(VPI) process, the transformer insulation class up to H
or C.

Type:

Isolation Transformers

Buck & Boost Transformers

Applications:

Our low voltage transformers are widely used in industrial
applications and in commercial and public buildings. They are also
used for adjusting the voltage from 690 V to 400 V or as isolation
transformers with a voltage ratio of 1:1, providing galvanic
separation.
